Span Drive Machinery Lifted Into Bascule Pier – August 26, 2017

During a temporary marine channel closure, crews installed large steel and mechanical components of the new Johnson Street Bridge.

The Arctic Tuk crane barge unloaded two machinery pieces called span drives into the bascule pier, which are the hydraulic motors that will raise and lower the new bridge.

Steel Fabrication – June 2017

The steel fabrication has experienced two delays and the current status at both the ZTSS and QuayQuip facilities is as follows:

  • The rings and lower counter weight are in the paint shop and undergoing surface preparation in advance of coating
  • The north and south trusses are still in the vertical fit-up assembly position – the position the bridge will sit in while in operation – to allow ZTSS to continue with the trial assembly.
  • ZTSS is currently installing outriggers and walkways on the exterior of the north and south trusses while it is in the vertical assembly position.
  • Span support segments are under fabrication at QuayQuip in Tianjin and are currently in various stages of machining. Trial fit-up is for these elements is scheduled to start on June 20.

Steel Fabrication – March 2017

With the horizontal fit-up completed, the trusses and the rings are now being stood upright in the position they will be installed in here in Victoria and are supported at each end. Many of the critical components such as the deck cross beams and counterweights are installed and their dimensions are checked. This will allow the engineers to check their calculations to ensure the steel fabrication meets the design standards.

Steel Fabrication – August 2016

The steel fabrication process has advanced to the trial fit-up stage. Project director, Jonathan Huggett, is currently in China during one of the key steps in the steel fabrication processes. The steel “fit-ups” are currently taking place to ensure that all the pieces of fabricated steel fit together. They will be fit together horizontally and vertically and then machined flat to ensure they all fit together properly.

Progress is also being made on the orthotropic steel deck, the counterweights that will help balance the bridge when it’s raised and lowered and the outriggers that will secure the pedestrian walkways to the bridge.

The pictures below are aerial views of both the north and south rings being trial fitted to the north and south trusses. These form both sides of the bridge structure.  The components are laid flat to fit the truss to the ring. The interfaces have to be machined flat until the fit is nearly perfect. The assembled components will then be stood up vertically and the fit up process will be carried out again. While the components are in these positions, various welds and attachments are being made, which could not be easily done while inside the fabrication shop.

The steel fabrication continues to progress with the majority of the work now being focused on completing the rings. In order to work on both sides of the rings, they need to be flipped over. The following series of photos show how the rings are flipped over outside the steel fabrication facility using a large crane.

Bridge Machinery – February 2016

The project steel engineers (Hardesty and Hanover) inspected the bridge machinery during a visit to Steward Machine in Birmingham, Alabama on December 10/11, 201 and significant progress is being made on all the bridge machinery that will help raise and lower the bridge. The pictures below show the various pieces and how they fit together.

Trucks are the upper pivoting part of the assembly that hold two wheels, and pivot on a machined shaft connecting it to the unit below. Below that is the intermediate and primary equalizers, each of which pivot to support the sections above.

Machinery4

Trucks and wheels are already fabricated and work on the sub-assembly of these elements has started. Primary equalizers and their bases are in fabrication.

Machinery3

The bases alone represent 40,000 pounds of steel each . The total assembled weight of each of the four bases is 240,000 pounds.

Machinery2

Drive shafts are installed in the hydraulic motors and are integrated with the pinion that drives the rack on the ring to open the bridge.

Steel Fabrication Update – September 2015

Steel fabrication continues and the crews are finalizing plans for a trial assembly of the bridge pieces to ensure they fit together properly.

Rings are progressing, with the north ring nearing completion and  the south ring is following close behind. On the south truss, the web and middle flange elements are fully fabricated and being fit into the truss before the final welding will start. This next step will seal the trusses permanently. The north truss is undergoing some final joint welding before it will be assembled into the final truss.

SteelSept14(1)

The lower counterweight for the bridge is assembled into major components and the final assembly of the lower counterweight will follow next month. On the steel deck, the floor beam fabrication is complete with the deck panel production to come next.

SteelSept14(4)

Overall, much progress has been made and the quality of work and quality control remains at a  high level as expected.

 

Steel Fabrication Plant Visit – May 2015

Steel fabrication resumed in March. An improved Quality Management Plan and Inspection and Testing Plan are now in place at the steel fabrication plant.

Regular inspections by the fabricator and the contractor’s quality control consultants are being conducted. This ensures that the bridge is constructed to the highest standard of the design. Any steel not meeting the highest quality and safety specifications will not be accepted.

Steel Fabrication – March 2015

Through 2014, much of the work on the Johnson Street Bridge took place on the west side of the bridge. In the coming months and throughout 2015, much of the construction work will shift to the east (downtown) side of the bridge. As the specifics of each construction phase are determined, the public will be informed and made aware of upcoming impacts to the public.

 

Steel Fabrication Restarts

Steel fabrication for the Johnson Street Bridge has restarted. An inspection last July found that some aspects of the steel fabrication had been undertaken outside of the design specifications, so the fabrication of steel was paused.

 

OrthotropicDeckPanels

Regular quality inspections will be routinely conducted by the fabricator and the contractor’s quality control consultants on the steel fabrication throughout the entire process to ensure that the bridge is constructed to the highest standard of the design. Any steel that does not meet the highest quality and safety specifications will be not be accepted by the City.

InspectionOfQualityWelds

The steel bridge has six main components: two rings, two forward trusses, a counterweight and the steel deck. The counterweight and steel deck connect the ring and truss structures together to form the complete bridge. After each ring and truss element are fabricated, they will be laid horizontally, assembled and tested. This process will be carried out on each truss and ring and then the same process will be repeated on the components in the upright position.

RingFlangePlates

After the span has been erected, assembled and measured in position, the machinery responsible for the raising and lowering of the bridge will be installed. The various bridge components will then be painted and packaged for shipping from Shanghai to Victoria on an ocean freight vessel.
